OU.02H]The table below shows the amount of money earned by Florida, in 2007, due to the Kennedy Space Center. Type of EarningAmount earned (in million dollars)
Commodities purchased from businesses703
Income paid to households1,100
Total direct income1,800

Based on the table, it can be concluded that commodities purchased from businesses make up
Florida's main source of earning from Kennedy Space Center
Florida's only source of earning from Kennedy Space Center
more than half of Florida's total direct income from Kennedy Space Center
less than half of Florida's total direct income from Kennedy Space Center

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
